The offer is formed on lessons from open health, mentioned Scott Charney of the firm's Trustworthy Computing team.
It is written to plunge into botnets - networks of putrescent computers beneath the manage of cybercriminals.
Putting machines in proxy solitary confinement would end the expansion of a pathogen and enable it to be cleaned.
"Just as when an particular who is not vaccinated puts others' illness at risk, computers that are not stable or have been compromised with a bot put others at chance and stance a larger hazard to society," he mentioned in a blog post .
"In the earthy world, international, national, and local illness organisations identify, follow and manage the expansion of disease that can include, where necessary, quarantining people to prevent the infection of others.
"Simply put, you must be upgrade and sustain the illness of consumer gadgets related to the internet to be able to prevent larger governmental risk."
Botnets have turn the pest of the internet and a prime amongst cybercriminals.
Computers are recruited into a network when they turn putrescent with a virus. These are ordinarily distributed by criminals as attachments in e-mail messages, and as program downloads masquerading as bona fide programs.
Networks can include of a couple of hundred to a couple of thousand Windows machines. However, a few can enclose millions of PCs.
The networks are often beneath the manage of criminals who ordinarily sinecure them out to others for assorted means inclusive pumping out spam or ascent "denial of service" attacks against websites.
"Commonly existing cyber defences such as firewalls, antivirus and automatic updates for safety rags can lower risk, but they're not enough," wrote Mr Charney. "Despite the most appropriate efforts, many consumer computers are horde to malware or are segment of a botnet."
His proposal, presented at the International Security Solutions Europe (ISSE) Conference in Berlin, Germany, is for all computers to have a "health certificate" to infer that it is uninfected before it connects to the net.
"Although the conditions to be checked might change over time, stream experience suggests that such illness checks should make sure that program rags are applied, a firewall is commissioned and configured correctly, an antivirus program with stream signatures is running, and the appurtenance is not now putrescent with well known malware," he wrote in the combining paper .
If the illness credentials indicates a complaint the P.C. could be stirred to download a omitted vegetable patch or refurbish its anti-virus settings.
"If the complaint is more major (the appurtenance is spewing out rouge packets), or if the user refuses to create a illness credentials in the initial instance, other remedies such as throttling the bandwidth of the potentially putrescent device, might be appropriate."
However, he said, that slicing people off the internet wholly "could well have deleterious consequences".
"An particular might be using his or her internet device to meeting crisis services and, if crisis services were not available due to insufficient of a illness review or certificate, amicable acceptance for such a protocol might righteously wane.
"But ample similar to a unit phone might require a cue but still enable crisis calls to be done even without that password, putrescent computers might still be permitted to rivet in certain activities."
Graham Cluely, of safety definite Sophos, mentioned that a few ISPs had formerly throttled a few users suspected of having infections.
"They wallop off users who look similar to they are sending considerable figures of spam e-mails - an denote of being segment of a botnet," he told BBC News.
Whilst it solves the problem, he said, it can result in problems for P.C. users.
"The dare then is what the bad aged user does," he said.
"They can't obtain on the net to download fixes."
He moreover mentioned that there was a danger that many people would regard that any summary revelation them that they had an infection on their appurtenance was a scam.
The draw close is used around the world. In Japan, for example, more than 70 ISPs have formed the Cyber Clean Center, that contacts users and provides safety program to prevent serve infections.
Other initiatives exist in France and Australia.
Microsoft mentioned that to make its outline work itwould need 4 steps, inclusive defining a illness computer, formulating a devoted network for illness certificates and anticipating a way for ISPs to routine and deed on them.
Relevant authorised frameworks would moreover be needed, it said.
But Mr Cluley questioned either Microsoft was most appropriate placed to suggest such safety measures.
"Microsoft doesn't have a unblemished record when it comes to security," he said.
"It has softened over the years, but every month they have to let go a package of updates.
"There might be a few who would say that Microsoft shouldn't be on the internet until they obtain their own residence in order."
